if yes what characteristicks must the fertilazers have ? {what in growing and what in flowering}

i dont think you need a room 4 meters x 4 meters for 1 plant.

perfect stop right there. then there is no need to explain or go into details. you be the judge.

Just my experience: In half that space I had 12 plants vegging, now they're on 12/12, found 7 fems out of 12, and this's all been done under a 400w HPS. I'd say you could get maybe 16 plants under a 600w
